What oil do you use?

Hi All,

After doing some brief searching online I found Pennzoil Platinum or Ultra rated well and above Mobil 1 in most cases. Also looked at some UOA's that seem to also support Pennzoil over Mobil 1. I ended to picking up some Pennzoil Platinum full synthetic from Walmart for $25 per 5qt jug and went in to the dealer to have the oil changed with my own oil. I have 24 oil changes I had built in to my financing which came out to about $15 an oil change. And the 7 qts needed for the change is about $35.

Seems like a good deal to me at about $50 total per synthetic oil change.

Anyways, back on topic. I noticed while I was at the dealer today that they sell the same Pennzoil Platinum in the parts department. I assume I ended up purchasing the same as the dealer uses, but for quite a lot less. I was quoted $90 for a synthetic oil change.

What oil are you using and anyone have Used Oil Analysis for their JGC?

Re: What oil do you use?

Pennzoil Ultra and a Wix oil filter. I did 3000 mile oil change intervals for the first couple. I'll probably push those out to 5,000 miles now.

I also get my oil at Wally World. They have the best price on the bulk jug.

Planning on doing a UOA? I think i'm going to follow the service intervals and go 6 months on the Pennzoil Platinum, which will prob be 5k miles for me, then send it off to Blackstone to be analyzed. I was shocked at how much more the oil costed at O'reilly's and online...

Amsoil Synthetic and NAPA Gold filter.

No UOA on the first oil change as I did it after only a couple thousand miles. Will run a UOA through Blackstone on the next oil change.

Re: What oil do you use?

Where's the dead horse? Nothing wrong with the question but opinions are like $&$ holes... Everyone has one. You're jeep will be fine with whatever you put in it provided you do so within reasonable intervals dependent upon your driving.

Haven't seen many UOA's for the JGC. I don't consider those as opinions. Although I agree peoples initial choice to pick an oil can be bery subjective. Thanks.

Re: What oil do you use?

Mobil 1 synthetic in all my vehicles I have owned. Once the 4 free oil changes at the dealer are done on my Jeep, i will switch to Mobil 1 synthetic and do it myself.

Re: What oil do you use?

I've used Royal Purple in all of my cars (since Royal Purple's HQ is literally right down the street from me.) along with a Wix filter.

Re: What oil do you use?

I've been running Mobil 1. It's $26 for 5 quarts at Walmart, and since I don't drive a ton of miles, I figure why not.

I'm not really opposed to using a different synthetic, but figured for the small difference in price why not go with Mobil 1. It's not like I just bought a used Corolla with 100k, ya know?

Are you going by the reminder or 6 months/8k?

Re: What oil do you use?

I have recently switched to Pennzoil Platinum Ultra in my Hemi. It seems to be the best oil on the market right now. If you are planning to keep the car for a long time, premium oil does make a difference. If you are just going to trade it in after a few years, sure, don't bother.

I changed the oil at 1,800 miles and have been doing it subsequently at 6,000 intervals and sending every sample to Blackstone for analysis. 6,000 does not seem to be a problem for the oil.

The samples at 7,000 and 13,000 miles still showed a significant (but decreasing) amount of break-in metals. The most recent sample @19,000 was clean.

Incidentally, the local dealer flat out lied to me about the oil they were using. They initially told me they were using Pennzoil synthetic, and when at the next oil change I asked for the exact product name because I was doing the UOA, the tech looked uncertain for a bit and ultimately, nervously revealed they were actually using "Siegel Titan", some local rebranding of cheap bulk oil. Really pissed me off. That might explain the 7,000 and 13,000 miles samples. The one at 19,000 was Mobil 1. I really should have made a bigger deal about it, but I was so pissed at them I just decided to never go back there unless it was for a warranty issue. This was Faricy Boys in Colorado Springs.
